    0. ensure remote server enables remote port fwd on non-loopback ip

    ```bash
    #/etc/ssh/sshd_config
    GatewayPorts yes
    ```

    2. ssh

    ```bash
    ssh -R [remote_port]:[destination_address]:[local_port] [username]@[ssh_server]
    ```

    3. check listening hosts from remote server

    say remote_port is `18000`:

    ```
    $ ss -plunt | grep 18000
    Netid State Recv-Q Send-Q Local Address:Port Peer Address:Port Process
    tcp LISTEN 0 128 0.0.0.0:18000 0.0.0.0:* users:(("sshd",pid=2714723,fd=10))
    ```
